Faith in God is spelt shraddha in Hinduism. We must possess 100% faith in God to gain success in spiritual life. Similar as one can detect the presence of a flower by its fragrance, we can also detect presence of God in day-to-day affairs of life simply by possessing 100% faith in God.
Those who did not believe in God always had a bloated ego. It is this ego that blocked their path to take inner journey towards God. Existence of God in cosmic system cannot be denied. If we exist it is due to existence of souls atmans. If souls’ atmans exist, so does God Almighty.
All souls’ atmans were God Almighty in miniscule form, an intrinsic part of God Almighty.
Believing in God is different from having faith in God. Most religious practitioners believe in God but they failed to start their journey towards God Almighty. Spiritual travelers who possessed a very high degree of faith in God, made their spiritual journey comfortable, easier by doing so.
In absence of faith in God spiritual travel is totally ruled out. Indulging in spirituality particularly sacred texts of Hinduism like Bhagavad Gita and Upanishads (independent spiritual treatises) one realizes the true value of having faith in God (shraddha in Hinduism). Most scientists’ world over failed to recognize presence of God as their faith in God was minimal or did not exist.
I many times countered my father on the issue of existence of God. He was a scientist of world calibre having invented a foundation technique that benefited our country India immensely. Still, in matters relating to God he always expressed his bloated ego and said he did not believe in God. When I persuaded him why he went Jain temples on religious occasions if he did not believe in God, his answer would be I would believe in God but show me first.
I started my journey towards God when six years of age. My faith in God at that time was absolute 100%. Even if God Almighty himself came disguised to dislodge me from my path, I would have not. Mounted with this power of faith I finally succeeded in reaching end of spiritual journey 37 years of age, when I realized self, realized god forever.
